Should I restore from iCloud or iTunes when upgrading to iPhone 6?

Hi, I have a quick question. I got a new iPhone 6 Plus. There are two options, restore from iCloud or iTunes. I have all my contacts, photos, calendar, etc in iCloud and want to keep them there.

If I restore from iTunes to get all my apps and everything, will those items still stay in iCloud?

It's best to restore from iTunes, it is much safer and much much quicker as the iCloud depends on your internet speed. And yes if you restore from iTunes all your data stays in the cloud as well.

Thank you!

  • Itunes help regarding CD's and upgrading IOS? I recently got an Iphone 5 after years of being an android user and i love it! But the problem is, when i used android i just bought Cd's that i wanted rather than buying select songs off of itunes. So i uploaded all of my CD's (along with a few video game soundtracks that aren't on the itunes online library) and now with IOS 7 on the way, will i have to re- upload all of my music from CD's again when i upgrade my ios?
